依据我国现行法律的规定,代位权的客体仅限于到期债权,并且该到期债权必须具有金钱给付内容。这种规定由于过于狭窄而无法解决市场经济迅速发展所带来的诸多问题,如抵押权等担保物权是否应该被纳入代位权客体的范围之内?对目前我国有关代位权客体的规定如何认定和处理?笔者认为,采用目的性扩张的方法进行漏洞补充,以使目前的法律规定足以解决实务中的诸多问题。在维护债权人债权的基础上,平衡债权人和债务人及第三人之间的利益关系,从长远看符合市场经济的长远发展。 According to the current law of our country, the object of subrogation is limited to maturing creditor’s rights, and the obligee’s claim must have money to pay. Such provisions are too narrow to solve the problems arising from the rapid development of the market economy. For instance, should the security interest such as mortgages be included in the object of subrogation? How to determine the current provisions on subrogation in our country? And treatment? The author believes that the use of purpose-based expansion of loopholes to supplement, so that the current legal provisions sufficient to solve many problems in practice. On the basis of safeguarding the claims of creditors, balancing the interests between the creditors and the debtors and the third parties will be consistent with the long-term development of the market economy in the long run.
